    I started rotating my BSSID weekly after I learned Apple and Google abused it to track the location of people and devices.

    Permanent hardware or software IDs, such as the Windows GUID or machine-id on Linux (systemd) are inevitably abused for surveillance sooner or later.

      The same physical location showing a different SSID every week but the surrounding ones not changing would be deanonymizing you much more aggressively.

      People mostly don't change SSIDs or even move networking hardware - e.g. AirBnBs.

      Edit: and also are you still carrying a smart phone while doing this? The device which has GPS and a cloud internet connection?
